About this app

Duo Mobile works with Duo Security's two-factor authentication service to make logins more secure. The application generates passcodes for login and can receive push notifications for easy, one-tap authentication.

Additionally, you can use Duo Mobile to manage two-factor authentication for other application and web services that make use of passcodes.

Note: For Duo accounts, Duo Mobile needs to be activated and linked to your account before it will work. You will receive an activation link as part of Duo's enrollment process. You may add third-party accounts at any time.

Additionally, we will request access to use your camera for the sole purpose of scanning QR codes when activating accounts. Accounts can be activated by other methods if you choose not to do so.

License agreements for third-party Open Source libraries used in Duo Mobile can be found at https://www.duosecurity.com/legal/open-source-licenses.

I wish I could give this a higher rating, but the fact that it's not compatible with the current versions of the Galaxy Watch or basically anything other than Apple Watches is pretty infuriating. As much as my institution requires a DUO push to get into any and everything I would love to be able to accept the notification on my smartwatch instead of having to find my phone each time. Such a disappointment and annoyance to deal with many, many, many times in the work day.

It's very annoying that we have to have 2FA, but Duo is one of the least annoying ways of doing it. There should be a feature in the settings which lets you turn off the sound effect. I would like to turn off the Duo push notification sound, still have the push notification, but leave notification sounds from other apps on my phone turned on.

If you're required to use it, it's fine. It's an okay general two factor code generator, but suffers for privileging a small number of sites with icons and primary labels, while everyone else gets a white circle and "third-party site." (You do set the visible account name, do you can distinguish them.) Backing up to Google Drive works fine. Ironically, may have problems restoring Dua-specific sites. If I could set the primary label and icon, I'd recommend it for general use.
